Sash-cord attachment fixture



Dec. 3, 1940. 'r. P. GUMPER SASH-CORD ATTACHMENT FIXTURE Filed May 15, 1940 INVENTOR THEODORE P. GUMPER ATTORNEY Patented Dec. 3, 1940 UNITED STATES T r ore-10E SASH-C'ORD ATTACHMENT FEXTURE Theodore P. Gumper, St. Louis, Mo. Application May 15, 1940, Serial No. 335,225 6 Claims. (01. 16-202) This invention relates generally to a certain new and useful improvement in sash-cord attachment fixtures.

My invention has 'forits principal object the provision of a fixture "uniquely constructed for facilitating the speedy and convenient attach,- ment to the sash of a sash cord either upon initial installation or subsequent replacement or renewal thereof.

My invention has for a further object the provision of a fixture of the type stated which is simple in structure, which may be economically and cheaply manufactured, which'may be readily and conveniently installed in window sashes, which may be manipulated with simple tools and by an inexperienced or unskilled person, which entirely obviates the expensive necessity of removing the entire window sash for replacing a broken sash cord, and which is highly efiicient in the performance of its stated functions.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawing:

Figure 1 illustrates a window-frame and sash in fragmental elevation equipped with a sashcord attachment fixture constructed in accordance with and embodying my present invention;

Figures 2 and 3 are enlarged perspective views of the companion or component members of the fixture;

Figure 4 is an enlarged longitudinal sectional view of the fixture in operative or installed position in a window-sash;

Figures 5, 6, and 7 are transverse sectional views of the fixture taken, respectively, along the lines 5-5, 6-6, and 1-'! of Figure 4; and

Figure 8 is a transverse sectional view of the fixture illustrating the respective components in unlocked position.

Referring now in more detail and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, the sashcord attachment fixture comprises a main or outer member A constructed preferably of phosphor bronze or other suitable sheet-metallic material pressed, stamped, or otherwise fabricated in the form of a partially cylindrical shell or casing having a suitably elongated wall I arcuate in cross-section with its margins sufficiently spaced circumferentially for providing a socalled throat a of reduced transverse or circumferential dimension relatively to the diametrical dimension of wall I The wall I, along its said longitudinal or throat margins, is provided with outwardly flaring divergent lips 2 and, at its one or lower end, is provided with a diametrall enlarged peripheral flange 3, which is curled over and inwardly in the formation of a channel-shaped annular roove or recess 4, the wall I being centrally provided with a pair of longitudinally spaced screwreceiving apertures 5, all as best seen in Figures 3 and 5 and for purposes presently more fully appearing.

Co0perable with the shell or casing A, is a companion, sleeve-like member B consisting of a section of metallic tubing having an external diametral size for somewhat snugly though rotarily fitting within the member A, the wall 6 of the tubular member Bbeing segmentally cut awa for a substantial portion of its length in the provision of an opening 1 to facilitate cordinsertion. At its one or upper end, the wall 6 of tube B is provided with diametrally registering nicks or slots ,8 and at its other or lower end is provided preferably integrally with a radially outwardly presented tongue 9 sized for fitting snugly though shiftably within the annular groove or channel 4, the tongue 9 having a socalled circumferential width less than the circumferential or transverse dimension of the throat a of member A. Intermediate the lower extremity of the opening 1 and its lower end, the

sleeve or tube B is provided with a plurality of suitably spaced inwardly and downwardly projecting pointed prongs ID, for retentive engagement with the inserted end f a sash cord C, all as presently more fully appears and as best seen in Figure 2, the member B being preferably of suitable length for normally projecting slightly above the upper end or extremity of the shell A when the members A and B are operatively assembled one within the other, as best seen in Figure 4.

In use and operation, a pair of shells or casings A is suitably mortised, and by means of screws or the like ll secured, in the frame-engaging or slide faces of, for instance, a lower window sash D adjacent the upper extremities thereof, with the respective throats a presented outwardly, as best seen in Figures 4, 6, 7, and 8.

A respective sash cord 0 at its free end is then threaded through the sleeve B and suitably engaged with the retaining prongs I 0. The particular sleeve B is then endwise inserted within a fixed shell or casing A with the tongue 9 ac- 2 commodated by and fitting for slidable movement in the throat a, as shown in Figure 8.

When the sleeve B has been fully lengthwise inserted into the shell A, a suitable tool, not shown, but preferabl of the spanner wrench type, is inserted into the slots or nicks 8 and the sleeve B axially rotated approximately a half turn, swinging the tongue 9 int engaging relation with the walls of the groove 4.

Thus the cord C is efiiciently, though readily detachably, engaged with the sash D for effecting the raising or lowering thereof.

Should the sash cord C be broken or otherwise require replacement, the sleeve B may be suitably rotarily oscillated for registering the tongue 9 with the shell-throat a, when the sleeve B may be conveniently pulled from the shell A, the one cord C disengaged from the prongs l0, and a new cord C readily installed in the manner as set forth.

The fixture fulfills in every respect the objects stated, and it should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the fixture may be made and substituted for those herein shown and described without departing from the nature and principle of my -invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A sash-cord attachment fixture including, in combination, a cylindrically shaped shell adapted for securement in a window-sash and havin a concentric groove adjacent one end, a tubular cord-receiving, member adapted for removable lengthwise disposition within the shell, and tongue means on the member for detachably engaging the shell-groove.

2. A sash-cord attachment fixture comprising, in combination, an open-end cylindrically shaped shell adapted for securement in a window-sash and provided at an end with a diametrally enlarged inwardly opening peripheral groove, a tubular cord-gripping sleeve adapted for axial disposition within the shell, and a tongue on the sleeve for. engagement with the shell at said groove for detachably securing the sleeve within the shell.

3. A sash-cord attachment fixture comprising, in combination, an open-end cylindrically shaped shell adapted for securement in a window-sash, the shell having a longitudinally extending throat and provided at an end with a diametrally en-,

larged peripheral groove opening into said throat, a co-operable cord-gripping sleeve adapted for axial disposition within the shell, and a tongue on the sleeve shiftable in said throat for engagement with the shell at said groove for detachably securing the sleeve within the-shell.

4. A sash-cord attachment fixture comprising, in combination, an open-ended receptacle adapted to be mortised into a window sash and provided at its irmer end with a detent-groove, a co-operable cord-gripping sleeve adapted for axial disposition within the receptacle, and means on the sleeve engageable in thegroove for releasably locking the sleeve within the receptacle.

5. A sash-cord attachment fixture including, in

combination, a shell of substantially U-shaped' cross-section adapted for securement in a window-sash and having a concentric groove adjacent one end, a tubular cord-receiving member adapted for removable lengthwise disposition within the shell, and tongue-means on the member for detachably engaging the shell-groove.

6. A sash-cord attachment fixture comprising, in combination, a shell adapted for securement in a window-sash, said shell including an elongated arcuate wall member having spaced parallel margins and outwardly turned flanges adjacent said margins for engagement with the sash, said wall member being provided at an end with a diametrally enlarged inwardly opening peripheral groove, a tubular cord-gripping sleeve adapted for axial disposition "within the shell, and "a tongue on the sleeve for engagement with the shell at said groove for detachably securing the sleeve within the shell. l
